CD4516BF datasheet by Texas Instruments

CD4516BF Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD4516BF can handle?
  The CD4516BF can handle clock frequencies up to 10 MHz, but it's recommended to limit it to 5 MHz for reliable operation.
• How do I ensure that the CD4516BF is properly reset during power-up?
  Connect the Reset (R) pin to VCC through a 1kΩ resistor and a 10nF capacitor to ground. This ensures a clean reset during power-up.
• What is the recommended operating voltage range for the CD4516BF?
  The recommended operating voltage range for the CD4516BF is 4.5V to 5.5V, with a typical voltage of 5V.
• Can I use the CD4516BF with a 3.3V supply?
  While the CD4516BF can operate at 3.3V, it's not recommended as it may not meet the specified timing and logic levels. Use a 5V supply for reliable operation.
• How do I interface the CD4516BF with a microcontroller?
  Use a 5V-tolerant microcontroller and ensure that the microcontroller's output pins can drive the CD4516BF's input pins. Use a level shifter if necessary.
